"cloud-init failed to complete after 10 minutes of waiting. This suggests a bug…"
I'm trying to boot the 22.04 live server from a bootable partition and after a time it fails with the message from the title. The partion is mounted on “/dev/cdrom”.
There is a “nocloud” folder set as parameter for the kernel in “grub.cfg, loopback.cfg” that contain the files necessary for autoinstall.
In the cloud-init logs looks like the files are loaded but in subiquity logs I found the error bellow.
Attached the logs and the used configuraton.
